We have things like the internet, personal computers, smartphones.

The internet opened up the marketing and selling side of real estate and this next wave of web3 will open up and expand another layer of it. 

Plus you need to ensure your guests are offered all of the creature comforts like cable, internet, toilet paper, coffee, shampoo, etc.As others have suggested, spend some time getting educated here on the forums, reading books, and listening to podcasts.When you're ready to make a move, make sure you are mindful of the competition within the sub-market, and the local regulations around short term rentals.

You can create a real mess by getting legal contracts from strangers on the internet.

The internet is one of the biggest contributors to this; easier to "otherize" people.

The Seller pays their commission, they are market experts, they provide an unemotional and objective opinion, they are expert negotiators, you'll have a second set of eyes to see things you miss, and they can write the contracts to protect you and conform with law.Second option would be to use an attorney.Getting legal advice for major purchases from strangers on the internet isn't wise. 

Way too complex for internet pundits!

And even now, most hotels are trying to get away from doing daily cleanings, not to mention “resort” fees at a lot of places where all that is included is high speed internet.

Most bankers are only familiar with loans for personal residences.Sometimes you can find them in an internet search.
